DOOR-KNOB AND ESCUTCHEON.

SPECIFICATION forming part of Letters Patent No. 335,349. dated February2, 1886.

(Broth-l.)

To all whom it may concern:

Be it known that I, ORVELLAS H. GILBERT, a citizen of the United States,residing at Newark, in the county of Essex-and State of New Jersey, haveinvented certain new and useful Improvements in Door-Knobs andEscutcheons; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon,which form apart of this specification.

The object of this invention is to provide door-furnitureviz.,door-handles, escutcheons, &c.of improved construction, whereby theparts thereof are held more firmly together, can be adapted to differingcircumstances, as described hereinafter, and also manufactured moreeconomically.

The invention consists in the construction and combination of thevarious parts thereof, substantially as illustrated in the drawings anddescribed and claimed hereinafter.

As shown in the drawings, embodied in two sheets, Figure l is a plan ofthe under side of the escutcheon. Fig. 2 is a section taken through linew of Fig. 1. Fig. 3 is a plan of a portion of the escutcheon. Figs. 4,5, and 6 are respectively a plan, side, and end elevation of thereversible plate; and Fig. 7 is a plan of the nut-lock5 and Fig. 8 is alongitudinal section of Fig. 1 through the escutcheon, rose-plate, 8:0.

Similar letters of reference indicate corresponding parts in each of thefigures.

In carrying out my invention I cast the escutcheou A, rose B, and shank0 preferably in one piece, substantially as illustrated. In thedepression D, formed by the rose, I provide two slots, 1) b--one onopposite sides of the bolt-hole d-placed, preferably, as indicated moreparticularly in Fig. 3, in which, as will be noticed, the slots are notin a line, so that the latch-levers on opposite sides of the door willnot interfere. IVithin the depression D,

I arrange a reversible plate, E, having a central depression, 6, adaptedto receive a nut and nut-lock with a slot, e, on one side thereof and arecess or depression, e*, on the opposite side, said recess and slotcorresponding with the slots 1) b in the depression D, the said platebeing adapted to be reversed, so that the recess e of said plate willrest in the slot 1) in the rose and the slot 6' correspond with the slotb, or vice versa.

Extending through the knob F, shank, hole d in the rose, and theperforation in the plate E is a bolt, G, provided with anut, g, on theinner end thereof, which holds all the several parts firmly together. Awasher, S, is arranged on the squared end of the shank, having lugs sextendinginto the knob, which prevents the said knob from turning on thebolt. To hold the nut in position and prevent its loosening, I arrangebetween the nut and the bottom of the depression 6 a plate, H, having anarm, h, which projects into the recess e, and thereby prevents saidplate from turning. The plate is then turned up on one side against thenut g, as shown in Fig. 1, holding the same iinmovably. Each side of theslot 6 is provided with downwardly-projecting lugs 6 perforated, asshown in Fig. 5, or slotted, as in Fig. 2, to receive a pin, j, upon thefinger piece or lever J, which is arranged within the slot 6, asillustrated in Figs. 1 and 2. The use of this lever is set forth in aprevious patent granted to me May 30, 1876, numbered 177,933, beingemployed in operating certain locking mechanism.

The object of having the reversible plate is, that the lever can bechanged from right to left, as desirable, and secured upon the doorwithout necessitating any special change in construction, the furniturebeing adapted to be arranged either upon the right or left side of thedoor. The recess e serves to fill up either of the slots bb when thelever is in one of them, presenting a smooth surface at the outside, andalso provides a recess for the reception of the arm h of the nut-lock.

Having thus described my invention, what I claim, and wish to secure byLetters Patent, 1s-

1. In door-furniture, the combination, with a roseplate provided withslots therein, of a reversible plate adapted to hold a latch-actuatinglever in pivotal relation therewith, said lever extending through eitherof the slots in said rose-plate, for the purpose set forth.

2. In door-furniture, the combination, with a rose-plate provided with aslot on each side of the shank, of a reversible plate adapted to closeup one of the slots in the rose-plate and to hold a latch-actuatinglever extending through the other of said slots in the roseplate inpivotal relation with the said reversible plate, for the purposes setforth.

3. In door-furniture, in combination, a slotted rose-plate andknob-shank cast integrally, a knob, a reversible plate adapted to hold alever extending through a slot in said roseplate in pivotal relationtherewith, a latchactuating lever, a bolt passing through said knob,knob shank, rose, and reversible plate, and a nut-lock arranged inConnection with the bolt and nut and adapted to be turned up againstsaid nut, for the purposes set forth.

4. In door-furniture, in combination, aslotted rose-plate and knob-shankcast integrally, a knob, a reversible plate having a depressedportion,"e adapted to close one of the slots in the rose-plate, and aslot corresponding with the other slot in the said rose-plate, havinglugs e on each side thereof, a latch-actuating lever pivotally arrangedin the slot in the reversible plate, as set forth, and extending beingarranged and operating for the purpose herein set forth.

5. In door-furniture, the combination, with a knob, knob-shank, bolt,and nut, arranged substantially as herein specified, of a nut-lock, forthe purposes herein set forth.

6. The combination, in door-furniture,witl1 a knob, knob-shank, bolt,and nut, of a nutlock having abolt-perforation therein and an arm, andadapted to be turned up against the nut, for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this15th day'of July, 1884.

ORVELLAS H. GILBERT.
